The arrangement of the periodic table is related to the electron configuration of the atoms of each element. Electron configurations represents how electrons are distributed. For instance, the neon atom has the electron configuration of 1s^2 2s^2 2p^6.
We have to calculate amount of zinc formed in the given reaction.
The amount of zinc formed is 16.47 g.
The balanced chemical reaction between copper and zinc nitrate is as follows:
2Cu (s) + Zn(NO₃)₂ (aq) → Zn (s) + 2CuNO₃ (aq)
From the reaction it is clear that one mole Zn is produced from two moles of Cu.
Atomic mass of copper is = 63.5 g and atomic mass of zinc is = 65.38 g.
As per reaction, 2 X 63.5 g= 127 g of copper produces 65.389 g of zinc. Therefore 32 g copper will produce g = 16.47 g of zinc.
Magnesium burns with oxygen to give magnesium oxide based on the following reaction:
2M<span>g</span>+<span>O<span>2 </span></span>........> 2Mg<span>O<span>(s)</span></span>+<span>energy
</span>From the periodic table:
molecular mass of magnesium = 24.3 grams
molecular mass of oxygen = 16 grams
From the reaction:
2 x 24.3 = 48.6 grams of magnesium are required to produce 2(24.3+16) = 80.6 grams of magnesium oxide.
We can know the amount of magnesium oxide produced from 8 grams of magnesium by simply doing cross multiplication as follows:
amount of magnesium oxide = (8 x 80.6) / 48.6 = 13.267 grams
